Nature Antimatter catches a wave at SLAC
A study led by researchers from the US Department of Energy's SLAC National Accelerator Laboratory and the University of California, Los Angeles has demonstrated a new, efficient way to accelerate positrons, the antimatter opposites of electrons. The method may help boost the energy and shrink the size of future linear particle colliders -- powerful accelerators that could be used to unravel the properties of nature's fundamental building blocks.

Nature Scientists discover atomic-resolution details of brain signaling
Scientists have revealed never-before-seen details of how our brain sends rapid-fire messages between its cells. They mapped the 3-D atomic structure of a two-part protein complex that controls the release of signaling chemicals, called neurotransmitters, from brain cells. Understanding how cells release those signals in less than one-thousandth of a second could help launch a new wave of research on drugs for treating brain disorders.

Physics Review Letters New 'molecular movie' reveals ultrafast chemistry in motion
Scientists for the first time tracked ultrafast structural changes, captured in quadrillionths-of-a-second steps, as ring-shaped gas molecules burst open and unraveled. Ring-shaped molecules are abundant in biochemistry and also form the basis for many drug compounds. The study points the way to a wide range of real-time X-ray studies of gas-based chemical reactions that are vital to biological processes.

Nature Communications Study finds a way to prevent fires in next-generation lithium batteries
In a study that could improve the safety of next-generation batteries, researchers discovered that adding two chemicals to the electrolyte of a lithium metal battery prevents the formation of dendrites -- 'fingers' of lithium that pierce the barrier between the battery's halves, causing it to short out, overheat and sometimes burst into flame.

Nature Researchers hit milestone in accelerating particles with plasma
Scientists from the Department of Energy's SLAC National Accelerator Laboratory and the University of California, Los Angeles have shown that a promising technique for accelerating electrons on waves of plasma is efficient enough to power a new generation of shorter, more economical accelerators. This could greatly expand their use in areas such as medicine, national security, industry and high-energy physics research.

Nature Materials Study sheds new light on why batteries go bad
A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought -- and that the benefits of slow draining and charging may have been overestimated.
The results challenge the prevailing view that 'supercharging' batteries is always harder on battery electrodes than charging at slower rates.

Nature Communications Buckyballs and diamondoids join forces in tiny electronic gadget
Scientists have married two unconventional forms of carbon -- one shaped like a soccer ball, the other a tiny diamond -- to make a molecule that conducts electricity in only one direction. This tiny electronic component, known as a rectifier, could play a key role in shrinking chip components down to the size of molecules to enable faster, more powerful devices.
